Apple Watch distance accuracy?

[Dootamie]

I still haven't been outside to run yet so I really have no idea what distance I'm running. My Apple Watch says just over 3 miles (which is 5k) but seeing as I run on a treadmill I'm not sure I believe it. What experiences have other treadmill runners found?

I doubt the watch is right. What speed setting do you have on the treadmill, and how long are you running?

I'm running for 30 minutes plus the 10 minutes warm up/cool down and it's set at 5.5km/hr

30 mins at 5.5km/hr is an easy calculation: divide the speed by two to get 2.75km.

Apparently Apple watches are the most accurate fitness trackers. Read the reviews on google. They all say the same.

I would be really shocked if all I’ve run in 40 minutes is 2.75km!!! I think the issue is the treadmill!! I’m going to map a 5km outdoor walk and that’ll solve this mystery 😜

GPS accuracy doesn't matter if you're only in one place running on a treadmill.
